What is the Longevity Research Library?

The Longevity Germany Research Library curates recent peer-reviewed studies on longevity, nutrition, exercise, sleep, and supplements. Each study is rated by evidence strength: Strong, Moderate, or Preliminary.

How are evidence levels determined?

Evidence levels are based on study type (meta-analysis, RCT, cohort study), sample size, journal impact factor, and reproducibility of findings.

Losing Your Sense Of Smell May Signal Faster Muscle Decline With Age

In adults aged 71 to 82, those who had lost their sense of smell lost grip strength faster over seven years. Men with anosmia also lost more quadriceps strength, though women did not show the same leg muscle effect. The link suggests smell loss may be an early warning sign of neuromuscular aging.

Exercise Lowers One Key Inflammation Marker in Frail Seniors, But Not Others

Looking at dozens of trials in older adults with frailty or muscle loss, researchers checked whether exercise calmed chronic inflammation. Exercise meaningfully lowered TNF-alpha, an inflammatory protein linked to muscle wasting. But it did not budge two other common inflammation markers, IL-6 and CRP. So exercise helps with inflammation in frail seniors, but only partially.

Why Losing Muscle With Age May Raise Your Cancer Risk

Healthy muscle releases tiny packets called extracellular vesicles that actually suppress tumor growth. As muscle shrinks with age (sarcopenia), it sends out fewer of these protective packets. In flies and mice, this helped tumors grow more easily. Exercise reactivated the pathway that produces these anti-tumor vesicles.

Regular Exercise Cuts Death Risk Even in Older Adults With Muscle Loss

Older adults with sarcopenia (age-related muscle loss) or trouble with daily tasks faced a much higher risk of dying. But those who met the WHO's activity guidelines saw that risk drop sharply. The pattern held across studies in the US, Europe, and China.

Resistance Training Plus Amino Acids Beat Either Alone for Muscle in Older Women

In healthy women aged 65 and older, combining resistance exercise with essential amino acid supplements for 12 weeks increased muscle mass more than doing either one alone. The combo group also showed the biggest improvements in fitness tests and the best shift in muscle-related hormones. Inflammatory markers dropped too, with one key marker only declining in the combined group. Each intervention helped on its own, but pairing them produced clearly stronger results.
